Splicing means for faced insulation batts

In a roof/ceiling insulation system for a metal building wherein a plurality of spaced parallel purlins are supported by and extend perpendicularly to a plurality of spaced parallel I-beams, spaced parallel insulation supporting tubes are suspended from the purlins and extend parallel to the main beams, and faced fibrous insulation batts are strung over the insulatin supporting tubes and main beams, means for splicing adjacent ends of two of the insulation batts together above one of the main beams and securing said ends with respect to said one main beam, said splicing means comprising a push-on splicing member mounted on an upper flange portion of said one main beam and presenting a flat backing portion extending vertically upwardly therefrom, and a pair of clamping strips respectively securing said ends of the insulation batts to opposite sides of said backing portion.
